SRAM is the key element used in digital circuits. It is also used as a cache memory in computers, automatic modern equipment like mobile phones, modern appliances, digital calculators, digital cameras, so that the requirements of high-speed advanced memory or embedded memory lead to the development of low-voltage SRAMs. The paper has introduced the design and simulation of the distinctive source-based sense amplifier which is a peripheral circuit for static random access memory (SRAM) that has to amplify the data which is present on the bit lines during the read operation. Simulation of the proposed design has been implemented using 20 nm FinFET technology on the Cadence Virtuoso Tool with a supply voltage of +0.4 V. The main advantages from the proposed design circuit are less power consumption and display of minimum sense delay in sensing the data from SRAM when compared to the existing design circuit. A comparison is drawn between the proposed circuit and the existing design circuit.
